Supplements should not replace a balanced diet, however, certain individuals may have specific nutrient deficiencies or unique dietary needs that can be addressed with supplements. For example, vitamin D supplements can be beneficial for those with limited sun exposure. However, indiscriminate use of supplements without medical guidance can be ineffective or even harmful. It's important to consult with healthcare professionals to assess individual needs, consider potential interactions or side effects, and determine the appropriate use of supplements to complement a healthy lifestyle and promote overall wellbeing.
